To all whom it may concern: section 1 is substantially Z shape in form,

Said sections 1 2 3 are preferinterior of the conduit. It desired,the insuably formed of rolled-steel plates and of the lators may be fastened to the bottom of the cross-sectional form shown. As shown, the conduit by screws or bolts 21., fitting in resea or notches 11 formed in the bases F out said base or foot piece rises nidard having a shaped openrmed therein. and opening through its In the sides of said opening are ries of grooves or notches 12, which orts for the wires 13.

They are arranged at any desired distance apart and, as will be seen from the drawings and the foregoing description, are supported rigidly in position.

By removing the cover-plate over any particularsection of the conduit the wires therein can be readily examined, repaired, or attended to as desired.

Preferably the conduit is provided with a lining 15 of insulating material, so that in case an electric conductor should be broken between two of the insulating supports therefor there will be no danger of the metallic walls of the conduit becoming charged with electrici'ty. This insulating lining may be applied to the lower face of the cover-plate 3, as well as to the bottom and side walls of the conduit.

By reference to the drawings, and particularly to Figs. 1 and 3, it will be seen that the conduit-section 1 is of such height that its lower end can be secured at such a depth as to prevent any danger of the line of curbing being affected by frost during the winter sea son. The flange 4 projects outwardly sufficiently far to receive direct pressure from quite a body of earth placed aboveit, as well as from a portion of the gutter, as shown in Fig. 1.

The entire structure, it will be noticed, is well braced, so as to resist pressure, and consists of a minimum number of parts, each formed of very strong, durable, but not excessively-heavy material.

The cross branch or lateral conduit represented in Fig. 7 is also formed of light steel rolled plates, assembled to form a trough-like conduit of the form shown and provided with a cover-plate similar to that hereinbefore described.

The main conduit may be provided at suitable distances apart with lateral house connections, one of which is shown in Fig. 2. These house branches may be formed of a tube, one end of which is secured in a suitable opening or aperture in the rear wall of 1' 1e conduit.

hereinbefore described, the conduit is preferably formed of rolled-steel plates or bars, although any other suitable material be employed.

wing thus described the invention, and without limiting myself to the exact details illustrated, what is claimed as new, and desired to be secured by Letters Patent, is-

1. in a combined curb and conduit, the combin ation of a metal plate or bar having a main vertically-extending portion forming the face of the curb and provided at its upper edge with a rearwardlyextending substantially horizontal flange, a second metal plate or bar secured to the rear side of the aforesaid plate and forming the bottom and rear wall of the conduit, and a cover or top covering the space between and resting on the upper-edges of said front and rear plates.

2. In a combined curb and conduit, the combination of a metal plate, substantially Z shape in cross-section, arranged to form the face of the curb and provide a rearwardlyextending flange at the upper edge thereof, a second plate, having an angular cross-section, secured against the rear side of the vertical portion of the first-said plate and forn1- ing with the upper portion of the first-said plate the bottom and side walls of the conduit, and a removable cover-plate resting on the upper edges of said plates.

3. The combination of two rolled steel plates or bars connected by bolts or similar means and forming a vertical curb and a conduitinrearand at the upper end of said curb, and a removable cover-plate extending across and covering the space between the upper edges of said plates.

4. In acombined curband conduit, the combination of a series of rolled-steel plates, substantially Z shape in cross-section arranged end to end and with their middle portions substantially vertical, joint-plates connecting the ends of adjacent sect-ions and secured to the rear face of the vertical wall and to the under face ofthe bottom flange thereof, a second series of connected plates, angularin cross-section, secured to the rear face of the first-said plates above the plane of the upper ends of said joint-plates, said two series of plates forming a curb and a conduit in rear and at the upper end thereof, and removable cover-plates adapted to close the conduit formed as aforesaid.

5. The combination with a conduit, of a series of conductor-sopports arranged within the conduit and each consisting of an upright or standard having a socket or recess formed in and opening through its upper end, the

, sides of said recess being grooved or notched to provide a plurality of seats or holders for electric conductors, and a retainer having a depending section extending into said socket or recess and laterally-projeoti11g flanges resting on the upper end of the standard.

The combination with a combined metal curb and conduit, of a series of conductorsupports, of insulating material, arranged within the conduit and each consisting of a standard having a socket or recess formed in and opening through its upper edge, the

of the embodiment of the invention herein l sides of said socket being serrated to provide a plurality of seats for electric conductors, a In testimony whereof I have signed my retaining device supported on the upperend name to this specification in the presence of of said standard and having a depending protwo subscribing witnesses.
